The field of Physical Medicine and Motor Rehabilitation (PMMR) is a medical specialty that deals with the diagnosis and treatment of different pathologies that affect the human body mobility. This process is characterized by the repetition of movements becoming dull and off-putting for patients under treatment. Over the past few years, new strategies have been introduced, including virtual games, aiming at making this process more fun and motivating. This paper presents the development of a mobile device for using virtual games that support the PMMR professional. It will be used both in the clinical setting as well as at home taking ergonomic and usability issues into account. We intend to offer professionals and their patients a chance to take advantage of the motivational potential of virtual interactive gaming enabling patients to undertake physiotherapy sessions in a more simple and convenient way.

The aim of this paper is the development of a new technological solution, for the automatic characterization of the yarn mass parameters (linear mass, diameter, and hairiness) based on image processing and computer vision techniques. A preliminary study for the detection and distinction between loop and protruding fibers is also presented. A custom-made application developed in LabVIEW from National Instruments with the IMAQ Vision Toolkit was used to acquire, analyze and process the yarn images. Some experimental results using cotton and polyester yarns were performed and compared with a commercial solution for validation. The presented approach allows a correct yarn parameterization improving products' quality in the textile industry. © 2015 Elsevier Ltd. All rights reserved.

In this work a mechanism for detection of stairs and stop wheelchairs was studied to avoid the approach of the wheelchair to the stairs or other dangerous places previously defined. The main purpose was allow to the people with mental disease, in manual wheelchairs, more liberty, without being dependent on a standing care of another person to avoid accidents. The brake system is composed by rim brakes, similar with that ones in bicycles, which are automatically activated by a sensor projected to detect dangerous places surrounded by a red line. This sensor start the solenoid movement reducing the speed of a wheelchair until its complete immobilization. The conceptual system is capable to stop a standard manual wheelchair until 3.26 seconds, with a braking distance of 1.09 meters. © 2015, Editura Cefin. All rights reserved.
